1'0 a/ZZ whom, it Ilz/ay] concern:

Be it known that I, THOMAS H. MAO-4 DONALD, of Bridgeport, Connecticut, have 1nvented a new and useful Improvement in a.

nectcd to the diaphragm, the whole being ar:

ranged so that the recording-style or the reproducing-style can be shifted, the one out of contact with the record-tablet and the other into contact, or vice versa.

More specifically stated, the invention consists of a single diaphragm, preferably mounted in a suitable casing or head, which casing or head is capable of being tilted for a slight distance upon a' pivot or axis, on which it is supported, so that the diaphragm can be shifted into two different planes. On this v diaphragm is secured a cutting-style forthe purpose of making a record, and a reproducingstyle (fpreferably rounded or spherical in form) or rubbing over a previously-made record to reproduce sound, the relative posi-- tion of the two styles being. such that when the diaphragm lies in one plane the recording.-

' style only will rest against the record-tablet,

and when the diaphragm lies -`in the other plane the recording-style will be shifted out of contact with the record-tablet, and the rel vproducing-style .will be brought into contact therewith. Any suitable means may be employed for shifting and retaining the diaphragm into either one of the two positions above mentioned. As here shown, the diahragm head or. casing is connected to a tuular shank, whose exterior surface, is approximately that of a zone ofv a sphere, said shank being inserted a Short distance into the open end of the'conveying-tube of the reproducer and pivotally connected to said tube.

Reacting between the diaphragm-casing and a suitable seat, preferably formed in thewall of the tube of the reproducer, is a sti spring, while on the other side a cam-lever is pivoted to the walls of the tube, the parts be' ing so adjusted that when the cam-lever is thrown into one position it permits the spring to throw the diaphragm-casing, and with it the diaphragm, into position to bring the recording-style in contact with the record blank or tablet, the tension of the spring being resisted on the opposite side of the cam-lever of other suitable abutment. When it is desired to shift the recording-style out of contact with the record-tablet and bring the reproducing-style in contact therewith,the camever is thrown down or shifted on its pivot, thereby tilting the diaphragm-casing, and

with it the diaphragm, into av different-plane,

and compressing the spring above mentioned. This action brings the reproducer style into operative position on the record-tablet.

The inventive idea involved may receive a variety of mechanical expressions, one of which, for the purpose of illustration, is

shown in the accompanying drawings, but it is to be understood that such drawings are for the purpose of illustration only, and are not designed to deiine the limits of the inthis purpose. t will also be understood that some features of the invention are not limited to a structure wherein both a recording and a reproducing style is employed. r

In the drawings, Figure 1 is a vertical `sec' tion through the center of the reproducer- `head and the neck or tube supporti-ng the same, showing the diaphragm in a -position, to bring the recording-style in Contact with the record tablet or blank. Fig. 2 is a view similarto Fig. 1 with the parts in position to throw the recording-style ont of contact with the record-,tablet and bring the repro- 'ducing-style into operative relation therewith, and Fig. 3 is a bottom plan view of Fig. 1.

Referring to the drawings, in which like reference-numerals indicate like parts, 1 is the reprodncer head or casing, having the diaphragm 2, mounted therein in any suitable or usual way-as, Jfor example, between gaskets 3v and 4. This diaphragm-casing 1 is provided at its back with a neck 5, having the exterior portion of its walls rounded,V

preferably into forni approximating that of n vention,'reference being hadvto the claims for l IOO opposite to the reproducer-head by a suitable joint 8, though any other desired forni of point between the neck 7 and its support ir. ay

e employed. The neck '5 is secured inthe'- end of tube 7 by a pivot 1.1, that"`is parallelwith the diaphragm. The spring 9 reacts between. the back of the reproducercasing and any suitable abutment. 10, here. shown as formed on the wall oi"Y the neck. 7. This spring 9 takes. bearing.. upon. thereproducer-casing at one side of pivot. 11.. Onthe opposite side of: the neck 5f from. the

spring 9 a cam-lever 12,. here shown as a. lbell-crank lever, is pivoted to. anv ear or lug.

13, pmjectingfrom the wall. of. the tubular neck 7.. The torm of the cam-lever 12 andv its position with relation to the diaphragmcasing l is such that when-it is in: one position, as shown in. Fig. 1, the face 14 of.v the lever 1.2 bears against the back of thediaphragm-casing, and this face 14 is at such a distance from the pivot 15. ofv the lever 12 as to allow the spring 9V to. expand. and throw the casing into a position here shown asa proxiniately parallel with the axis of t e tube 7. When, however, the cam-lever 12 is shifted into the positionA shownV in Fig. 2., the face 16 bears upon the back ofthe diaphragmcasing, and said casingis shifted to a position to compress the spring 9 and throw the said casing intoa plane at an angle to that of the axis of. tube 7. This tilting Aof the casing upon its pivot is due to. the fact that theface 16 of lever 12- is farther away from the pivot 15 than is face 14 Two. styles-viz., a recording-style 17 and- Any suitable means for connecting the styles`r 17 and 18 to the diaphragm may be en:- ployed. As here shown, suc-li means are in the form oi a clip 19,01?l nietal or other suitable material, having a plurality of sockets of chambers for receiving one end of the res ective styles, the styles being so arranged t at oniy one of them can contact with the record-tablet at a time. This clip' 19 is secured to the face of the style-in any suitable Way, as by cement. The particular form of clip 19 here shown will be recognized as being substantially that showr and described in my United States Patent No. 683,958, with the addition thereto of a suitable socket for holding the reproducing-style 18.

Having thus described my invention, what I claim is- ,1. In a talking-machine, a combined ree corder" and reproducer comprising .a single diaphragm mounted to tilt upon a given axis,

and a recording and a reproducing style secured to said diaphragm, a spring acting to `turn the diaphragm in one direction, and

meansoperable to turn the diaphragm against the tension of said spring.

2.'. In a. talking-machine, the combination of a pivotally-mounted diaphragm-casing, a diaphragm supported therein, a spring reactving between said casing and a suitable abutvof a. diaphragm-casing having a tubular neck whose outer surface is inthe form of'a zone or a sphere, a sound-conveying'tube within which said neck is pivotally connected, a diaphragm in said. casing, a style mounted on said diaphragm, and means shifting said casing upon said pivot into a plurality of planes.

5. Ina talking-machine, the combination of a diaphragm-casing havinga tubular neck whose exterior is formed on the lines of a sphere, a sound-conveying tube within which said neck is pivotally mounted, a diaphragm insaid casing, a plurality of styles mounted on said diaphragm, and means shifting said casing upon said pivot into a plurality ot planes.
